Apples and oranges. You also need to factor in the weight of the engines and the reenforced fuselage you need to support jet engines. It's not just the fuel that is heavy. Electrical engines are really light and compact. The resulting planes can be much lighter.
Also electical engines can be throttled up and down with much better granularity. An idling jet engine still produces a lot of trust and burns a lot of fuel even before it leaves the ground. So the efficiencies you get from better control over the output are substantial as well.
Basically the current state of the art gives you a flight time of typically 1-1.5 hours with most electrical planes. If you double or triple that capacity through better batteries you basically get planes that can do short haul. The expectation is that that is basically happening over the next decade.
